6.3.3. Error codes
Error code may consist from up to 4 symbols. Ea
ch symbol may have values 0…8
Code
Description
Status of calculator
0 - no error, normal operation
1 - warning
– ending battery life
2- temperature difference is greater than the permitted limits
4- temperature difference is less than the permitted limits
8- electronics failure
Status of temperature
sensor 2 (return pipe)
0- no error, normal operation
4- short circuit
8- sensor failure (open circuit or short circuit)
Status of temperature
sensor 1 (flow pipe)
0- no error, normal operation
4- short circuit
8- sensor failure (open circuit or short circuit)
Status of flow sensor
0- no error, normal operation
1- no signal, flow sensor is empty
2- flow flows in an reverse direction
4- flow rate greate
r than 1.2∙qs (are displayed q=1,2qs)
8- electronics failure
Active error codes are added and simultaneously displayed, if it is detected more than one error
3 - corresponds errors 2 + 1
5 - corresponds errors 4 + 1
7 - corresponds errors 4 + 2 + 1
9 - corresponds errors 8 + 1
A - corresponds errors 8 + 2
B - corresponds errors 8 + 2 + 1
C - corresponds errors 8 + 4
D - corresponds errors 8 + 4 + 1
E - corresponds errors 8 + 4 + 2
F - corresponds errors 8 + 4 + 2 +1
In a case when value at least one digit of error code is
≥ 8 - calculation of thermal energy and summation of volume
of water and operation time without errors are stoping
In the case of the flow sensor error "4" -
duration of time, "when the flow rate q> 1.2 ∙ qs" is registered in addition.
6.4. Activating test mode
Destination of contacts of connector J
The 2-line,10-pole connector is on the calculator plate between temperature sensors and pulse input /output
terminals (see fig.A1, Annex A).
Destination of contacts of connector J is presented in fig. 6.3.
